ALSA: hda - Fix ADC input-amp handling for Cx20549 codec
commit 6b45214277bec2193ad3ccb8d7aa6100b5a0f1a9 upstream.
It seems that Conexant CX20549 chip handle only a single input-amp even
though the audio-input widget has multiple sources. This has been never
clear, and I implemented in the current way based on the debug information
I got at the early time -- the device reacts individual input-amp values
for different sources. This is true for another Conexant codec, but it's
not applied to CX20549 actually.
This patch changes the auto-parser code to handle a single input-amp
per audio-in widget for CX20549. After applying this, you'll see only a
single "Capture" volume control instead of separate "Mic" or "Line"
captures when the device is set up to use a single ADC.
We haven't tested 20551 and 20561 codecs yet. If these show the similar
behavior like 20549, they need to set spec->single_adc_amp=1, too.
